Barcodes and QR Codes Decoder in Python

By reading this piece, you will learn about the tips and tricks to generate one-dimensional barcodes in different formats as well as Quick Response code (QR Code) generation. Besides, this tutorial will outline the methods to decode both the barcode and QR Code using the same Python library. Previously, I have covered a tutorial on How to Generate and Decode QR Codes in Python which used OpenCV to decode QR Codes. In this tutorial, I will be using another module called pyzbar for decoding instead. Based on the official documentation, pyzbar is

“… a pure Python library that reads one-dimensional barcodes and QR codes using the zbar library, an open source software suite for reading bar codes from various sources, such as video streams, image files and raw intensity sensors. It supports many popular symbologies (types of bar codes) including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5 and QR Code.”

Based on the experiments that I have conducted, pyzbar performs better compared to python-opencv in terms of accuracy when decoding QR Codes. On top of that, pyzbar is able to decode barcodes as well.

Let’s proceed to the next section and start installing the necessary modules.

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

#python #anonymous function python #filter function in python #lambda #lambda python 3 #map python #python filter #python filter lambda #python lambda #python lambda examples #python map

Common Anti-Patterns in Python

Improve and streamline your code by learning about these common anti-patterns that will save you time and effort. Examples of good and bad practices included.

1. Not Using with to Open Files

When you open a file without the with statement, you need to remember closing the file via calling close() explicitly when finished with processing it. Even while explicitly closing the resource, there are chances of exceptions before the resource is actually released. This can cause inconsistencies, or lead the file to be corrupted. Opening a file via with implements the context manager protocol that releases the resource when execution is outside of the with block.

2. Using list/dict/set Comprehension Unnecessarily

3. Unnecessary Use of Generators

4. Returning More Than One Object Type in a Function Call

5. Not Using get() to Return Default Values From a Dictionary
